Fresh hacks every day
After seeing a Game Boy emulator for the first time, [Thijs] was amazed. A small box with just a handful of electronics that turns a Game Boy cartridge into a file able to be run on an emulator is simply magical. [Thijs] has learned a lot about GB and GBC cartridges in the mean time, but still thinks the only way to really learn something is to roll up your sleeves and get your hands dirty. Thus … [Read more...]
This single digit display is an old edge-lit module that [Ty_Eeberfest] has been working with. The modules were built for General Radio Company and have a really huge PCB to control just one digit. [Ty's] modules didn't come with that driver board, so he was left with the task of controlling an incandescent bulb for each digit. After a bit of thought he figured it would be much easier to just … [Read more...]
Here's an Android powered pen plotter that does it all. It was built by [Ytai Ben-Tsvi] to take with him to Maker Faire. He's the creator of IOIO, a hardware interface module designed to communicate with an Android device via USB (host or OTG are both supported). The physical hardware is simple enough. He draws on a pad of white paper using a felt-tipped marker. Located at the top of … [Read more...]
For those of you who might have forgotten, let's go over the rules of Centurion. The object of the game is for every minute, for 100 minutes, drink a shot of beer. It doesn't sound like a lot, but after completing the challenge you'll have had 3 liters of beer (or about eight and a half 12 oz cans) in just under two hours. When [Peter] played Centurion, he found the biggest problem was - … [Read more...]
We've been following the work of [Andrew Holme] and his homebrew GPS receiver for a while now. A few years ago, [Andrew] built a four-channel GPS receiver from scratch, but apparently that wasn't enough for him. He expanded his build last year to track up to eight satellites, and this month added a Raspberry Pi for a 12-channel, battery-powered homebrew GPS receiver that has an accuracy of about … [Read more...]
Do you ever wonder why geese always fly together in a V-shape? We're not asking about the fact that it makes the work load much less for all but the lead goose. We mean how is it that all geese know to form up like this? It's is the act of flocking, and it's long been a subject of fascination when it comes to robotics. [Scott Snowden] researched the topic while working on his degree a few years … [Read more...]
[Martin Raynsford] figured out a way to sneak some learning into a fun package. He did such a good job the test subjects didn't even know they were teaching themselves just a tiny bit of CNC programming. The apparatus above is a marble maze, but instead of building walls [Martin] simply etched a pattern on the playing field. The marble is a ball bearing which moves through the maze using a … [Read more...]
